There's this (not sure if it's your issue or not): https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=837155 If /var resides on a separate file-system which is unmounted before unattended-upgrade-shutdown is run, it may repeatedly (by default for 10 minutes) try to acquire it's lock-file but fail since the containing folder doesn't exist. For which the fix is a file /etc/systemd/system/unattended-upgrades.service.d/mounts.conf containing [Unit] RequiresMountsFor=/var/log Maybe irrelevant. Or not.
